Background: We aimed here to investigate the association between alleles and genotypes of APOE and Age-related macular degeneration (AMD) development. Materials and Methods: After ophthalmological examination, 120 patients with confirmed AMD and 120 healthy controls were enrolled in the study. The polymorphic segment of APOE gene was PCR-amplified and sequenced to determine the frequency distr...
the present study was aimed to identify the frequency of coagulase (coa) and thermonuclease (nuc) genes and staphylococcal enterotoxin a (sea) production among staphylococcus aureus isolated from various sources in shiraz. moreover, the correlation between the sea gene and coagulase and thermonuclease enzymes is also considered. a total of 100 s. aureus were isolated from various sources includ...
بررسی شیوع پلیمورفیسم rs 1049174 ژن NKG2D در بیماران مبتلا به سرطان پستان و مقایسه آن با افراد سالم
Introduction: NKG2D receptor is one of the activator receptors of immune cells. In humans, NKG2D gene has two single nucleotide polymorphisms (SNP)(rs1049174G>C). According to other studies, GG SNP makes a high affinity receptor for NKG2D ligands whereas, CC polymorphism reduces NKG2D affinity for their ligands. The present study investigates NKG2D SNPs in patients with breast cancer in Yazd f...
background and objective: high-level gentamicin resistance (hlgr: mic ≥ 500 µg/ml) in enterococci is mediated by aminoglycoside modifying enzymes which is mainly encoded by aac(6′)-ie-aph(2′′)-ia gene. the aim of this study was to evaluate the frequency of aac(6′)-ie-aph(2′′)-ia gene in clinical isolates of enterococcus facium and enterococcus faecalis collected from hospitals in northwest of...
